Description

この発明は、長尺体を捲回保持するとともに重量かつ大径の円筒形状のドラム体の設置方向の転換をなし、その周囲にクレーン等の吊上げ設備を有せずに該ドラム体を持ち上げて回転動可能に保持するドラム体の持上げ装置を組み付けてなるドラム体の回転支持台（ターンテーブルともいう。）に関し、併せて、該ドラム体の回転支持台を使用してなすドラム体の移送並びに設置方法に関する。本発明は特には、帯状部材（プロファイル）を捲回保持する帯状部材用ドラムに適用されて好適な回転支持台と該回転支持台を用いてなす帯状部材用ドラムの移送並びに設置方法に関する。 This invention winds and holds a long body and changes the installation direction of a heavy and large-diameter cylindrical drum body, and lifts the drum body without having a crane or other lifting equipment around it. The present invention relates to a drum body rotation support base (also referred to as a turntable) that is assembled with a drum body lifting device that is rotatably held. It relates to the installation method. In particular, the present invention relates to a rotation support base suitable for being applied to a belt-shaped drum for winding and holding a belt-shaped member (profile), and a method for transferring and installing the belt-shaped drum using the rotation support base.

古くなった下水道管渠の更生につき、帯状部材（「プロファイル」と称されている。）を当該既存の管渠の内面に螺旋状に巻き付けてライニングする下水道管渠の更生工法が行われている。
しかして、この更生工法の実施のために帯状部材を巻き取っておくドラム（すなわち帯状部材用ドラム）が用意され、施工現場の人孔（マンホール）の開口部の近傍に配されたドラム支持台のローラ上に該帯状部材用ドラムを載置し、ライニング作業の進行とともに帯状部材を帯状部材用ドラムより引き出しつつ、該帯状部材用ドラムに回転を与えて帯状部材を人孔中に降下させてゆくものである。
図１４はこの帯状部材の一例の断面を示す。その（ａ）図は合成樹脂（塩ビ樹脂）製の帯状部材２００の断面を示し、（ｂ）図は帯状部材２００相互の係合状態の断面を示す。すなわち、帯状部材２００は螺旋状に捲回されて相隣合う帯状部材２００相互を係合されて管状体（ライニング管）を形成する。２０２は係合部に介装される止水材である。
従来のドラム支持台においては、該ドラム支持台に載置された帯状部材用ドラムの回転のために当初より持ち上げられた構造となっている。このため、帯状部材用ドラムをドラム支持台に載置するのにクレーン等の吊上げ／吊降ろし作業装置が別途必要となり、使用に制限が加わり、設備の大規模化が避けられない。 Regarding the rehabilitation of old sewer pipes, a rehabilitation method for sewer pipes has been carried out in which a strip-like member (referred to as a “profile”) is wound around the inner surface of the existing pipe helix in a spiral manner and lined. .
Therefore, a drum support base is provided in the vicinity of the opening of the manhole at the construction site, in which a drum (that is, a drum for the belt-like member) for winding the belt-like member is prepared for carrying out the rehabilitation method. The belt-shaped member drum is placed on the roller, and the belt-shaped member drum is rotated and the belt-shaped member drum is rotated to lower the belt-shaped member into the human hole while the belt-shaped member is pulled out of the belt-shaped member drum as the lining operation proceeds. It is going.
FIG. 14 shows a cross section of an example of the belt-like member. The (a) figure shows the cross section of the strip | belt-shaped member 200 made from a synthetic resin (vinyl chloride resin), (b) The figure shows the cross section of the engagement state of the strip | belt-shaped members 200 mutually. In other words, the belt-like member 200 is spirally wound and the adjacent belt-like members 200 are engaged with each other to form a tubular body (lining tube). Reference numeral 202 denotes a water stop material interposed in the engaging portion.
The conventional drum support has a structure that is lifted from the beginning for the rotation of the belt-shaped member drum placed on the drum support. For this reason, in order to mount the drum for belt-like members on the drum support, a lifting / hanging work device such as a crane is separately required, and the use is restricted, and the scale of the equipment cannot be avoided.

そこで、本出願人は先に、特願２０１３−２３６７７２（以下、先行発明という）において、当該下水道管渠の更生に使用される帯状部材用ドラムの持上げ装置を提案した。
本持上げ装置によれば、施工現場においてクレーン等の吊上げ装置を要することなく、該帯状部材用ドラムを持ち上げ、かつ回転動可能に支持するものであり、画期的である（先行技術：実開昭６２−４８１１２号公報）。
しかしながら、該先行発明の持上げ装置によれば、搬送車両に積込まれる帯状部材用ドラムが大型化するにつれ、該搬送車両の荷台の制約により該荷台の幅方向には設置できず、荷台の長手方向となり、これに伴い該持上げ装置も荷台の長手方向への設置が余儀なくされ、施工現場での運送車両の設定に制約が生じることとなる。 Therefore, the present applicant has previously proposed a belt-like member drum lifting device for use in the rehabilitation of the sewer pipe in Japanese Patent Application No. 2013-236772 (hereinafter referred to as the prior invention).
According to the present lifting device, the belt-like member drum is lifted and supported so as to be rotatable without requiring a lifting device such as a crane at the construction site. Sho 62-48112).
However, according to the lifting device of the preceding invention, as the belt-like member drum loaded on the transport vehicle increases in size, it cannot be installed in the width direction of the load platform due to restrictions on the load platform of the transport vehicle. Accordingly, the lifting device is also required to be installed in the longitudinal direction of the loading platform, and the setting of the transportation vehicle at the construction site is restricted.

実開昭６２−４８１１２号公報Japanese Utility Model Publication No. 62-48112

本発明は先行発明を更に発展させたものであり、搬送車両の荷台の制約を受けることなく、先行発明の持上げ装置を使用することを目的とするものである。
本発明はこのため、当該持上げ装置に支持される帯状部材用ドラムの設置方向を変えることができる機能を付加することにより、具体的には、搬送車両の荷台に積込まれた帯状部材用ドラムの設置方向を変えることができる回転支持台を付加することにより、この目的を達成し得るとの知見に基づくものである。 The present invention is a further development of the prior invention, and an object thereof is to use the lifting device of the prior invention without being restricted by the loading platform of the transport vehicle.
For this reason, the present invention adds a function capable of changing the installation direction of the belt-like member drum supported by the lifting device, and specifically, the belt-like member drum loaded on the loading platform of the transport vehicle. This is based on the knowledge that this purpose can be achieved by adding a rotation support base that can change the installation direction of the.

The roller holding frame 51 includes a side wall plate 51a constituting a square wall and a bottom plate 51b fixed to the bottom portion of the side wall plate 51a, and thereby maintains rigidity. The bottom plate 51b has a constant area and is placed on the support (the lower plate 1 of the turntable T) with its friction surface. Further, the rear side wall plate 51a is rigidly connected to the fixed frame 52 with or without an interposed plate.
The fixed frame 52 is attached so as to surround the main frame 32 a of the y-axis frame 32. The fixed frame 52 is movable with respect to the main frame 32a, and is fixed to the main frame 32a with a fixing bolt a.
The roller portion 34 may be fixed (no movement) with respect to the main frame 32a of the y-axis frame 32. In this case, the fixed frame 52 is unnecessary, and the roller holding frame 51 of the roller portion 34 is directly rigidly contacted with the main frame 32a of the y-axis frame 32.
